At least in the somewhat old days, Linux was noexception to this.
The problem for initrds is that the job
For my sins, I have spent a modest amount of time testing how well a fewswitches did port mirroring . Thedepressing result was that neither of the switches I tested had portmirroring that worked really well for our needs, but on the other handit has given me an appreciation for the issues that port mirroring canhave.
(We use port mirroring for simple network traffic volume monitoring,and we would like to be able to use it for network debugging; at thetime I was investigating if we could use

There are a number of people who will sell you rather expensive networktap boxes (eg here ). Since hearingabout them and discovering the actual prices, I've felt that trafficmonitoring switches with mirroring ports (despite the VLAN issue ) and dual-NIC PCs running bridging software madethem pointless except for people with very high end needs; they wereneat in a theoretical way, but not something we would ever need inpractice, since the alternatives were perfectly good.
